VM clone network interfaces names changes
by Artem Tambovskiy
Hello,
I have a question indirectly related to oVirt - I have a VM with CentOS 6
running on my cluster, which has 6 virtual interfaces (eth0 - eth5). Now
its a time to do an upgrade to CentOS 7 based, and I did a VM clone to test
an upgrade process and was a bit surprised to see that now I have interface
names shifted eth6 - eth11. I would afraid that I'll run out of digits
soon :)
Anyway how to change the interfaces names back to originals and perhaps
prevent them form the further changes? I do understand that MAC address has
changed, but don't get why it changing the interfaces names.
Cleaning up everything from /etc/udev/rules.d/70-persistent-net.rules
doesn't really helped ..
Regards,
Artem

Downloading a disk image
by Kristian Petersen
I am trying to download a disk that I have on my oVirt cluster. When I go
into the Disks section of the web UI, I can click on it then click on
Download, but it never seems to actually download anything. I left it
overnight to see if it was just slow, but then nothing seemed to download
at all. It just seemed stuck where it was after clicking download the day
before.

How Many Logical networks supported
by p.staniforth＠leedsbeckett.ac.uk
Hello,
We are currently using oVirt for teaching and one of our requirements is for security such as IR PEN testing etc. We would like to create individual logical networks with a network profile that includes port mirroring, this is to reduce the amount of traffic they can see and the targets available.
We are looking to to add VMs into Affinity Groups so they will run on the same host to make the port-mirror work but don't no if there is a limit on the number of logical networks that is allowed/practical.
Thanks,
Regards,

Adding a new Host to Cluster via oVirt Manager fails with "No Route to Host"
by Markus Frei
Hello everybody
I am facing the following issue currently.
I am trying to add a new physical host to our cluster via oVirt Management Engine Web GUI.
Apparently communication between oVirt Engine and the corresponding host is working well, since all necessary packages will be installed successfully.
But after a while the installation process fails with the error "No Route to Host" and the host ends up in state "non operational".
I checked the network interfaces via Web GUI (Host -> Network Interfaces -> Setup Host Networks) and none of the interfaces are present.
In my opinion this is the main problem. It seems the interfaces are not being recognized.
I tried using a bond interface and a single interface with static configuration (IP, DNS, Gateway).
None of them worked.
Further Log Errors:

Any hints and suggestions are very appreciated!
Thanks in advance.

VLAN tagging with external provider networks
by anurag.porripireddi＠bigswitch.com
Hi,
I see that checking the "External provider" box whilst creating networks clears and grays out VLAN tagging. Is VLAN tagging for external provider networks not supported?
Thanks,

Resizing ovirt-engine disk
by Baptiste Agasse
Hi all,
We have a running ovirt installation on a SAN backend (installed in 4.0 via appliance, then updated to 4.1 and now in 4.2). At installation time we choose (or didn't change) the disk size and this one is about 10GB:
fdisk -l /dev/vda
Disk /dev/vda: 10.7 GB, 10737418240 bytes, 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000686fc
Device Boot Start End Blocks Id System
/dev/vda1 * 2048 20971519 10484736 83 Linux
Can we grow the ovirt-engine disk like any other managed VM ?
And if not, how can we grow the ovirt-engine disk out of standard installation procedure ?
Have a nice day.
Cheers.
Baptiste.

vNIC tagged VLANs and Bond VLANs support
by greg＠santconsulting.com
Hi,
We have a need to create a VLAN tagged vNIC over a Bond interface and allow that same VLAN to be accessible to a VM who's NIC is the same Bond. Our testing shows that once you create the VLAN tagged vNIC, the VLAN is no longer available to VMs over the bond. Below is the config we are trying to create.
VM#1
oVirt Interface = Bond0
Logical Network = vNIC70 (tagged VLAN 70)
VM Host Interface = eth0
VM#2
oVirt Interface = Bond0
Logical Network = Bond0 / Host based VLAN 70 tag as sub-interface (eth0.70)
VM Host Interface = eth0.70
Is there a way around this issue while supporting the requirement?
Thanks!

Info on HCI single host
by Gianluca Cecchi
Hello,
following this reference guide:
https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_no...
after having run with success the gdeploy based gluster setup, there is
Setting up Hosted Engine
Use the Ansible based installation flow of Hosted Engine to set up oVirt
within a virtual machine. The storage details should be provided as type:
glusterfs and connection path as: <hostname>:/engine (Replace hostname with
address of host on which installation is carried out)
What does exactly mean "Use the Ansible based instalation" ? Does it mean
using cockpit web ui? In this casae I suppose I have to choose:
Hosted Engine
Deploy oVirt hosted engine on storage that has already been provisioned
Correct?
Thanks,
Gianluca
